Pump Station Wet Wells: Minimum Storage Volume

When designing a pump station wet well, ensuring the correct minimum storage volume is critical for efficient operation and long-term reliability. Proper storage volume helps prevent pump cycling issues, optimizes energy efficiency, and extends pump lifespan—all essential factors in a well-functioning wastewater or stormwater system.

The minimum storage volume in a wet well directly impacts pump performance. If the storage volume is too small, pumps may cycle too frequently, leading to premature wear and higher energy costs. Conversely, an oversized wet well can cause excessive retention times, increasing the risk of solids settling and odor issues.

To strike the right balance, system designers must consider factors such as:

• Inflow rates – How much wastewater or stormwater enters the system.
• Pump cycle times – Ensuring optimal on/off cycles to prevent overuse.
• Wet well design – Proper configuration for smooth operation and minimal maintenance.

A well-designed wet well ensures efficient pump operation and reduces operational costs. Engineers typically calculate storage volume based on the pump’s flow rate and cycle time, ensuring the system meets performance requirements while minimizing wear and tear.
